What are pages?

- Pages are same sized pieces of logical memory of a program. Usually they range from 4 KB to 8 KB depending on the addressing hardware of the machine.

- Pages improve the overall system performance and reduces requirement of physical storage as the data is read in 'page' units.

Differentiate between logical and physical address.

- Physical addresses are actual addresses used for fetching and storing data in main memory when the process is under 

execution.

- Logical addresses are generated by user programs. During process loading, they are converted by the loader into physical address.
